“Garven's pilot ability is not an action”. I agree.
But still, it seems to me that a token represents an action to perform. Since the rule book states that you cannot perform the same action twice in a round, you cannot perform two focus. In the case of the presence of a stress token, which prevent you to perform any action or red maneuver, then Garven will grant a focus token to the stressed pilot … but without the ability for the pilot to use it.
Do I miss something?
